Definitely not for sale any more, as it was published by Psygnosis in 1994.
I am not aware of an A1200 floppy disk version - AFAIK the game was CD32 only. The controls make good use of the CD32 pad, so a joystick-based version would most likely have made for problematic key-prodding. Perhaps someone can confirm/correct.
I have the original on CD32. Amiga files only seem to take up 1.44mb of the CD - the 17 audio tracks run for 44 minutes, though!
Hope this info is of some use, Drake.
